Inventor: PALMER LEE
IPC: A61C1/00
Filed: 1991-05-03
Abstract: The invention relates to an irrigation system and method for delivering a selected one of multiple solutions to a treatment site.  The invention solves the technical problem of being able to positively verify the type of solution being administered. The invention solves these problems by providing a plurality of solution reservoirs (12) having a quantity of a solution (34), a selector valve (20) coupling a handpiece (14) to each of the solutions (34) and a pump (18) causing the solutions (34) to flow to the handpiece (14). Each solution (34) has a color which is distinguishable from the color of the other solutions (34) and the tubing (126) to the handpiece (14) is transparent thereby enabling the identity of the solution (34) being used to be verified. The irrigation system is a closed system with the pump (18) as well as a heater (19) for heating the solution (34) being situated outside of the flow path of the solution (34).

Inventor: MAZZIOTTI PHILIP J
IPC: F16C21/00
Filed: 1993-08-16
Abstract: ABSTRACT OF THE DISCLOSURE      A lubrication system is set forth for a universal joint. A cross of the universal joint has four trunnions extending therefrom along two mutually perpendicular lines.  Bearing cups are rotatably received on the ends of the trunnions and the cups, in turn, are held by universal joint yokes.  Lubrication passages extend from a central portion of the cross outwardly to cavities located at the ends of the trunnions.  A passage extension extends substantially through each cavity from the lubrication passage toward the end of the trunnion.  A lubricant retainer is of generally inverted U-shaped configuration and extends over the passage extension.  The retainer has openings near the bottom of the cavity and is centered in the cavity by a flange on the passage extension or by an outer flange at the edge of the retainer.  The retainer prevents air from being trapped in the bottom of the cavity so that the cavity will always be filled with lubricant.

Title: Work-modulated pacing rate deceleration
Inventor: SHELTON MICHAEL B
IPC: A61N1/365
Filed: 1993-03-25
Abstract: A rate-responsive cardiac pacemaker in which deceleration of the pacing rate is modulated according to recent patient activity or "work". Based on signals provided from an activity sensor in the pacemaker, the pacemaker maintains and periodically recomputes a Work value corresponding to the amount of patient activity detected over time. In response to a decrease in or cessation of detected patient activity, the pacemaker reduces the pacing rate, first at a more rapid deceleration rate, then at a lower deceleration rate, and then once again at a more rapid deceleration rate. The length of time during which the pacing rate is reduced at the lower deceleration rate is modulated according to the Work value maintained by the pacemaker. The work-modulated pacing rate deceleration occurs only if certain achievement criteria are met, the achievement criteria being specified in terms of the amount of time the pacemaker's target pacing rate exceeds a predetermined rest value, and the difference between the target rate and the rest rate.

Title: Temperature Compensation of Liquid-Crystal Etalon Filters
Inventor: PATEL JAYANTILAL S
IPC: G02F1/133
Filed: 1992-02-05
Abstract: A compensator for thermal or other uncontrollable effects in a liquid-crystal etalon filter (10). The narrow pass band of the filter is controlled by adjusting the amplitude (48) of an AC drive signal (44, 46) applied to the electrodes (22, 24) on either side of the liquid crystal (26) in the filter. An optical detector (36) detects the intensity of light (30) from a narrow-bandwidth input beam (34) passed by the detector. Electrical circuitry (40) determines the bipolar amplitude of the component of the light intensity that is at twice the frequency of the AC drive signal (the doubled-frequency amplitude) and adjusts the amplitude (48) of the AC drive signal in response to the doubled-frequency amplitude so as to reduce the doubled-frequency amplitude toward zero.

Title: A process and apparatus for treating a fluid
Inventor: WRIGLEY DAVID
IPC: C02F3/06
Filed: 1992-07-20
Abstract: Apparatus (1) for treating a fluid, in this case wastewater, comprising a vessel or tank (2), means (3) to supply the wastewater in an alternating sequence to the vessel (2), and a means (4) for oxygenating the bed of granular media (5) to provide aerated filter media. The filter bed is aerated during operation by air, oxygen enriched air or other gas being introduced at or adjacent the base (as viewed) of the bed through the means (4), which may be a perforated manifold, diffuser or the like extending substantially over the whole surface area of the bed (5). Also the bed (5) is a granular media such as natural minerals or blast furnace slag media to the surface of the discrete particles of which is attached bacteria and microorganisms (a biomass) which effects treatment of the fluid. The influent at (3) derived from sewage is counter current to the air, and is particularly a non-nitrified influent namely wastewater that has previously been treated to reduce the BOD (biological oxygen demand) and suspended solids concentrations. The blast furnace slag media (5) has an average particle diameter of 2.8-4.0 mm and a porosity of 13.9 %. In carrying out the process the periodic reversal of the flow through the filter bed maintains the concentration gradient of the microorganisms (biomass) substantially uniform as a desired concentration of microorganisms throughout the depth of the bed under all operating conditions in the embodiments illustrated. This provides for a uniform, efficient treatment of the sewage.
